3. Project Objectives
• To study the working principle of gas and smoke detector system
• To design and construct of the gas and smoke detector system and control system using
Arduino with Bluetooth module
• To implement gas and smoke design in the project
• At the very first time of smoke creation so that avoided the unwanted accident

4. • A smoke system is number of devices working together to
detect and warm people through visual and audio appliances
when smoke and carbon monoxide
• A smoke detector is a device that sence smoke , gas
Literature Review

5. The MQ-5 smoke sensor is sensitive to smoke and to the following flammable gases:
• High sensitivity LPG
• Natural gas
• Town gas
• Butane
• Small Sensitivity Alcohol, Smoke
Features of MQ-5 Smoke Sensor

6. • The MQ-5 has 4 pins: Vcc,GND,AO,DO
• Right Now I Will Only Deal With 3 pins.
• Here is how you should connect the MQ-5 to your Arduino
• Vcc to Arduino 5v
• GND to Arduino GND pin
• AO to Arduino analog pin A5
Connect MQ-5 Sensor

7. What is Aurdino
• ATmega328 microcontroller(8 bit)
• Input voltage 5v
• 32k Flash Memory
• 16 MHz Clock Speed• Operation on +5v
• 14 Digital 1/0 Pins(of which 6 are PWM)
• 6 Analog pins
• Arduino is an open source electronics platform based on easy to use hardware and
software.

8. Necessary Equipment
• 5V power supply
• Male to male to male to female jumper wires
• Arduino Uno
• Arduino Bluetooth Module
• Breadboard
• LED
• Buzzer220
• ohm resistor
• MQ-5 gas sensor

11. Application
.
• They are used in gas leakage detecting equipment in family and
industry
• It is suitable for detecting of LPG, natural gas, town gas
• Avoid the noise of alcohol and cooking fumes cigarette smoke.

12. Advantages
.
• Detects Products of Combustion
• Sensitive Enough to detect level of gases
• Detects gases prior to reaching lethal levels
• Produced between the Occurrences of detectable level and
detectable heat levelsDownload

13. disadvantages
.
• Can be Prone false alarms
• Must be mounted at a low level
• Can be Poisoned
• Not Suitable for areas where CO and CO2 andProduced the
functions within the area
• Cannot be considered as a universal replacement and thermal
detectors• High Cost

14. Conclusion
• Smoke detector is One of the easiest and low costly.
• Most of industries use it, Because it work fatly to protect and most effective.
• In future the use of gas and smoke detection will increases.
• In future we include Bluetooth Module.
• At finaly we complete this project using 3 sensor.
